atherosclerosis \ath`er*o*scle*ro"sis\
([a^]th`[~e]r*[-o]*skl[-e]*r[=o]"s[i^]s), n. [Gr. ? + -logy.]
(Med.)
a form of arteriosclerosis characterized by irregular fatty
deposits on the inner surface of large and medium-sized
arteries; the deposits are associated with fibrosis and
calcification of the inner layer of the arteries. Similar
conditions may be found in swine and fowl. The deposits may
become large enough to impede the blood circulation and in
some cases may restrict the blood supply to the heart.
